Referring to the drawings, 20 designates a wheeled frame bearing a container, vat or tank and comprising a bottom frame 2| horizontally positioned' and preferably made of angle iron rendered rust proof by galvanizing, enameling or otherwise. The side .angle bars 22 run longitudinally and are connected to the end angle bars 2.3f by welding or otherwise. Suitable parallel transverse cross members 24 are provided in the form of angle bars or otherwise and shown below thebars 22 and 23. Two pairs of angle bars 24 disposed closely adjacent and near the ends of the frame support swiveled casters 25 with cushion rollers if desired, these casters being adapted' to turn about. The frame is also reinforced by a bottom cross strip 26 which may The front corner posts, or upright the latter also connected to each other through the medium of gusset plates 30 Welded, riveted or otherwise secured in position. A longitudinal bar or rim 3 I is provided between the uprights 28 at the top of the wheeled frame and may also be of angle iron with a vertical outer iiange and a horizontal inwardly extending top flange. A longitudinal bar or rim 32 is provided at the top of the inside or back of the Wheeled frame between the corner posts 29 and may be of composite construction to form an inverted U- shaped member, but the top flange of the bar 32 extends outwardly as distinguished Jfrom the inwardly extending flange 3| and the other ange extends vertically at the inside for connection with the vertical members of the frame by welding or otherwise. The container, vat or tank is produced by means of a lining 33 which may also be fastened to the vertical anges of the bars 3| and 32, and as shown at 34, may be passed over the top flange of the bar 32 to extend outwardly and downwardly in spaced relation as at 35.150 form a channel member and also give increased strength and stiffness at the side and rim which is normally disposed toward the agitating machine and the ironing machine, as will be later described. The depending ange at this point is shown at 35, thus producing an inverted U-shaped guard rail with a depending flange at the outside. Vertical members 36 may connect the upper and lower portions intermediate the ends thereof with diagonal braces 31 outwardly thereof, all connected between the upper and lower bars 3| and 22 and 32 and 22, these being the bars which run horizontally and longitudinally of the wheeled frame.

An elevator frame is provided for the container, vat or tank of the wheeled frame and includes a platform or basket 38 consisting of longitudinal side bars 39 such as angle iron, connected to the end bars 46 with gusset plates 4|, if desired, by welding or otherwise. Cross strips or braces 42 may be arranged transversely between the bottom flanges of the longitudinal bars 39. Upright end posts 43 are provided intermediately of the ends and may be rendered rigid by inclined or diagonal braces 44 preferably at the front. The upright end posts 43 are preferably of fiat stock and the braces 44 are connected thereto near their upper ends and to the bars 46. The bar 39 will engage the bar 3| at one side of the wheeled frame having the container, vat or tank, to limit upward movement or displacement of the elevator frame or platform 38 while traveling vertically, but permitting removal thereof laterally or horizontally above the low side.

In order to provide means for detachably connesting the elevator platform, frame or basket to a hoist, the uprights 43 are provided near their upper ends and on their inner faces with buttons 45 shown of rectangular formation located horizontally and having reduced squared shank portions 46, these buttons being bolted or riveted through to the uprights 43 which are apertured for this purpose. One end of each head 45 is beveled or tapered as indicated at 4l.

A slatted removable bottom 48 is provided for the elevator frame or platform 38 and consists of spaced parallel transverse cleats 49 adapted to rest on the horizontal flanges of the bars 39 and 48 connected by closely adjacent spaced parallel strips 50 running longitudinally. This slatted bottom is adapted to be bodily placed within the elevator frame, platformor basket.

A key plate having a suitable aperture near one end is provided with a longitudinal slot 52 having an intermediate circular enlargement 53 produced by opposed concavities at the edges of the slot and the aperturefof the plate is connected to a chain or cable 54. Two of such plates and chains are provided, it being understood that these plates are designed to be detachably engaged with the buttons 45, the plates 5| being engaged with the buttons in the positions shown in Figs. 5 and 7 and then the plates turned vertically at a ninety degree angle by reason of the concaved recesses 53 so that the heads of the buttons will straddle the slots 52 and prevent displacement of the plates, but may be turned horizontally for disengagement thereof assisted by the beveled portions 41. The upper ends of the chains or flexible connections 54 are connected at 55 to suspension means including a suspension or truss frame 56 consisting of a horizontal bar 5l shown in the form of a pipe or tubular element having a central strut or upright 58 connected at its upper end by braces 59 to the ends of the bar 51 as through the medium of the I-bolts 55. The upright 58 above the connection of the braces 59 therewith has a hole 60 for engagement by a hook 6| swiveled at 62 to a block or weighted enlargement which forms a bumper as will be later described, and is in turn connected to a flexible connection or chain 63 operating to wind and unwind or be raised and lowered by a hoist 64 which may be of any suitable type. This hoist is shown suspended by a hook 65 from a hanger 66 at the ceiling or other elevated support and has a driven sprocket 61 operated by the reversing and reducing gear 68 from a motor 69. The chain, after passing over. the sprocket 61 is formed into a depending loop 10, one lap of which has connection at 1| to the motor casing with an interposed spring 12 to cushion the reversing or checking movements of the drive and elevator frame. A cable 13 carries the electrical energy to the motor or through a switch 14 provided for thus controlling the operation of the motor including the starting and stopping as well as the reversing thereof. A pivoted cross arm 'l5 is mounted between the switch box and the motor as shown in Figs. 14 and 17 and is limited in its movements by a stop pin 16. An up pull cord 11 is connected to one end of the cross arm 15 and a similar down pull cord 18 is connected to the other end While a pivoted fork 'I9 is mounted beneath the motor at the reducing and reversing gear to be engaged by the abutment or bumper 62 should the upward movement of the elevator platform proceed toy such position, in which instance the fork will strike the depressed portion of the cross arm I5 on either side of the pivot thereof and dispose of same in a neutral position thereby opening the switch to the motor. Brake shoes are provided on the motor casing to operate on the shaft thereof and are held by springs 8|, but adapted to be expanded by a shoe expander 82 and connected to the pivot of the cross armV 'l5 of the switch so that when the switch is in a neutral position the shoes will be engaged, but when the switch is operated to raise or lower the elevator platform the expander will separate the brake shoes so as not to retard the operation of the motor.

The hoist is disconnected from the elevator platform and basket after the latter is lowered into the container. vat or tank of the wheeled frame in the manner shown in Fig. 9 and by disconnecting the plates 5| from the buttons 45, the wheeled frame may be moved about and positioned adjacent to the agitating machineA 83. This machine has a horizontal drum or cylinder B4 with a door opening 85 and has a channel rail 86 at one side adjacent the door opening and may be connected to the wheeled frame byfa transfer plate B1 having a channel 88 to engage the channel 86 or other suitable bar at the side of the agitating machine and preferably so that the transfer plate will be inclinedv toward the low side of the wheeled frame. A channel 89 is provided at the other end of the transfer plate to engage the bar or channel 35 so that the damp wash laundry may be discharged from the agitating machine into. the tank orvat 33. The transfer plate is then disconnected and the wheeled frame moved beneath the hoist 64. adjacent or against the ironing machine or mangle indicated at 9i] and the plates 5I connected with the buttons 45 upon pulling the cable 18 to lower the same if not already down, or this connection may be made after some of the laundry has been removed from the top of the batch and fed into the ironing machine. As the supply is lowered the elevator frame may be raised by simply pulling on the switch cord l1v or lowered by pulling on the switch cord 18.

The ironing machineis shown provided with control or starting levers Sl and a clutch lever 92. The ironing cylinders are designated at 93 and 9d while 95 is a feed roller mounted on a shaft 96 in adjustable bearings 91 operated by screws 93 having suitable operating Wheels. A sprocket 99 on the shaft 96 is engaged by a chain mi! driven in any suitable manner by a motor or other driven part of the machine. Ribbon belts lill are trained on the feeding roller 95 and also around a small idler roller 102 and over an apron |83 which supports the upper laps of the belts. A weighted roller 104 engages the work or towels H25 as the latter are fed into the ironing machine in the manner depicted in Fig. 2 of the drawings. A ticket holder 'or 4clip 106 may be provided on the front or high side of the wheeled container on the bar 3l to hold the laundry tickets referring to the batch contained in the vat and being moved from the agitating machine and then passed into the ironing machine. By having the elevator platform or basket capable of being raised to the degree desired within the Wheeled container or tank, the operator can readily grasp the clothes while remaining in convenient position for feeding the laundry into the ironing machine and in this way the work is facilitated without needless bending over, and therefore the work may be carried on with greater facility and considerable economy.

In View of the foregoing it is thought that the construction and operation of the device will be readily understood and therefore further description thereof is omitted.
